Hi All,
We wish to create some kind of DR plan for our OVM 4.4.10.7-1.0.22.el8 environment.
Idea is to do storage replication of defined Storage Domains.
steps:
create LUN on storage
present LUN to OVM
create Storage Domain
put VMs on Storage Domain
on storage
replicate LUN to another storage [or the same storage]
Storage Domains contains OVF_STORE
Now, recovery
On live OVM
present replica of LUN
import Storage Domain
But we cannot import replica LUN. Where to look for errors? Is this action possible it
all?
Facts
OVM is the same version
Storage is the same vendor
LUN is browsable on SAN level and have differen WWIN, if we wish to add replicated LUN
like new Storage Domain. Adding new Storage Domain mean that LUN will be formatted ...
What I do wrong?

Hi,
I believe that when you replicate the LUN using Array Storage, *you also
replicate the uuid of the lvm* (volume group) that oVirt/Linux uses.
I believe this is the cause of not being able to import the new LUN as
Domain Storage.
You can view the logs on the host you chose to import the LUN (rescan
process). The file is located in */var/log/vdsm/vdsm.log*.
*My suggestion:*
1 - Create a new LUN
2 - Create a Domain Storage
3 - Replicate the data (disks) using some script or backup software such as
Vinchin
Cheers!

Hello Jorge,
Thank you for your answer, but it seems that during the import process oVirt cannot read
or see the contents of the LUN

First LUN is hosted engine LUN
The second LUN is the LUN I am trying to import and it is a clone of the third LUN
The third LUN is the LUN I cloned to the second lun from the list
The idea is to import the replicated lun in another ovirt cluster
ovirtA -> lunA
then storage replication of lunA -> lunB
replicated lunB import to ovirtB
10:46 a.m.
But in these logs there is no error yet, it only identifies the object...
The error must be further ahead.
